Giorgio Parisi – awarded this year’s #NobelPrize in Physics – discovered hidden patterns in disordered complex materials. His discoveries are among the most important contributions to the theory of complex systems. t.co/ggdbuauwcY

A trip also down the memory lane to my time as a graduate student of Oscar Lanford: The dyadic world t.co/N1UmyKu6HP appears naturally in dynamical systems like the solenoid (Smale-William attractor) or when doing integral extensions. I try here something with groups. t.co/Yo19csb0k9

@BenDeeBenDee @1austrartsua1 @AnalysisFact About non-uniqueness: it is unique when taking the canonical one, like 13/16 = [1,4,3] and not [1,4,2,1] even so 1/(1+1/(4+1/(3)))=1/(1+1/(4+1/(2+1))). It also does not affect the question mark sum. Using rationals only has the advantage that the numerical values are all exact

@1austrartsua1 @AnalysisFact I'm at the moment on an ``ultra finite trip" and refuse infinity. But since the function is monotone, one can just approximate an irrational number either from the left or right. For an irrational function it is defined as an infinite sum, but an ultra-finitist refuses this.

@paulcabbott Cool. I have not seen, but no surprise. Mathematica has almost everything already in.

One of the coolest and mysterious functions is the Minkowski question mark function. Lets call it F(x) on the interval [0,1] as it naturally defines a CDF. Even cooler is the corresponding PDF. It is probably singular continuous (no ac component in the Lebesgue decomposition). t.co/xKBEuqWbGU

A natural metric space (X,d) has a unique group structure (X,+,0) for which all group translations are isometries. The dihedral integers are natural. See t.co/h5OKVZzY6j and blog entry t.co/kazzYXTEM0
